I don’t know of any v/m that provides the same level (give or take) of nutrients that ration balancers do, that are also cheaper. Balancers are pretty cheap on an as-fed basis.
Fuel is between $1.45 and $1.93 a serving (depends on your serving size, and looking at the 40lb bucket
High Point Grass is $.82/serving at the 50lb bag size.
I get Triple Crown 30 for about $32, which means I’m paying $.64 per serving (I only feed 1lb). For comparison, I feed TC Sr to 1 horse, at $29/bag (I think? Maybe $27? Let’s use $27). At $27/50lb that’s $.54/lb. A minimum feed rate is 5lb - $2.70/day. I’ve never seen even a cheap bagged feed that was cheaper to feed - as designed - than any ration balancer. Even a super cheap feed at $10/50lb would still cost $1 to feed at a min of 5lb, compared to 1lb of a higher priced balancer at $.64 (so even more $ to feed than the less expensive balancers, in a per-serving basis).
With High Point Grass, I also needed to add Nutramino for the AAs. HT doesn’t have the full GA for the Fuel on their site, so I have no idea the lysine and methionine content, but there is some.
The new Triple Crown 30 Gold has zero soy, so is low in protein and AAs, which means you’d need to add them if you’re not feeding enough alfalfa or other source of higher protein (and your grass forage isn’t high enough).
Don’t forget that RBs are also in the range of 1200-1300 calories/lb, so not insignifcant. So, replacing pretty much any v/m supp is going to add a few calories.
Vitamin E - whether there’s enough in a RB OR a v/m supp entirely depends on the product. TC 30? 1000IU/lb .
Fuel? No idea since it’s not listed in the GA but is added.
High Point Grass? 750IU/serving
